RAILROAD-TIE.

' Specificationof Letters Patent.

Application filed September 10, 1909. Serial No. 517,121.

To all whom it my concern.

Be it known that I, THOMAS LEE EvERE'rr,

a citizen of the United States, residing at Fairfield, in the "county ofJefferson and State of Iowa, have invented new and-use- .fulImprovements in Railroad-Ties, of

which the following isaspecification.

This invention relates to railroad ties, the

object of the invention being to provide a substitute for the ordinaryWooden railroad tie now in common use.

The tie hereinafter described, comprises a concrete body combined. withrail holdi'ng means embedded in and forming a part of the tie, doingaway with the necessity of using the ordinary fish plates and bolts andeconomizing materially-in the cost of maintenance of the road byavoiding the necessity of tightening the bolts and fasteners from timeto time.

With the above and other objects in view, the invention consists inthe'novel construction, combination and arrangement of parts as hereinfully described,; illustrated and claimed.

. In the accompanying drawings :Figure l is a perspective view of arailroad tie embodying the present invention, showing a section of arailroad rail applied thereto.

Fig. 2is a detail perspective view of one of the cushions. Fig. 3 is asimilar view of one of the rail clamps. Fig. 4 is a detail perspectiveView of a double rail clamp adapted to bridge adjacent ties.

The body -of the tie indicated at 1 is composed of concrete and may bemade of any desired length, width and depth, the length being sufficientto support the. rails.

In connection with each tie, I employ a pair of yokes, each yokeembodying a pair of upwardly curving and inwardly facing braces 2 havingenlarged lower ends which are connected by a base 3 formed integrallywith the bracesas shown in Fig. 1 at the left hand end. The said base 3is recessed in its upper face as shown at 4 to provide forthe receptionof a cushion block preferably of wood. In forming the recess fl,shoulders 6 are left at opposite sides of said recess; which shouldersare received in oppositely located notches 7. formed in the cushion 5,as shown in Fig. 2. Inthis way the cushion is securely locked in placein the yoke and between the braces 2-. The yeizes at opposite ends ofthe tie are connected by a tie bar 8 indicated by dotted lines in Fig.

1, the yokes being secured to the tie bar by bolts or rivets 9 or in anyconvenient manner. The central portion of the tie bar between theyokes'is depressed in the form ofan inverted arch as shown at 10, thesaid depressed portion together with the entire tie bar being embeddedin the tie during the formation of the latter; The opposite extremitiesof the tiebar beyond the yokes are extended downward and are alsoembedded in the, tie.

In connection with each yoke, I employ a pa r of rail clamps eachembodying a tapering base .12 having an inclined upper surface 13; theclamp also comprises a \"er' tical 'or upstanding flangele adapted tobear against the side of the rail, and a curved or U-shaped bend 15which embraces the bottom flange of the rail, as shown in Fig. 1. Theupstanding part 14 is provided on its outer side with an interlockinglug 16 while the upper extremities of the braces 2 t are provided withslots 17 to receive the lugs 16 of the rail clamps. In this way, an in-Patented May31, 1910.

terlocked engagement is cfiected between the rail clamps and the braces,as shown in Fig. 1,

Instead of employing a separate pair of clamps for each tie, the clampsmay be elongated horizontally as shown in Fig. 1 or in other words saidclamps may be made of suflicient length to bridge a pair of ties inwhich case each clamp may be provided with a pair oflugs 16 to bereceived in the notches 17 above described.

cushions 5, when a train passes over the joint, the rail clamps bearwith greater tirinness and pressure against the rail and avoid anypossibility of the rail slipping adjacent to the joint. The joint alsoprovides for the necessary, expansion and contraction of the rails dueto changesin the veather as,

it may work lengthwise between the rail clamps when relieved of theweight of the train. The rails are associated with the c lamps'and tieby. sliding the clamps endwise into engagement with said rails and" tie.

The joint hereinabove described 1S especially valuable on curvedsections of a rail- "way' track as it not only provides forthe embeddedin the-tie body.

necessary contractionand expansion but also prevents the tendency of theouter rail 'to spread on acurve. It is also within the i scope of thisinvention to use the clamp upon a continuous bed of concrete instead ofseparate ties as hereinabove described.

1'. A railroad tie comprising a tie body of concrete, yokes eachcomprising a pair of rail braces and an integral base connecting saidbraces and formed with a cushion receiving recess between the braces,and a tie bar connectingthe yokes and having its central portiondepressed between the yokes and its opposite extremities projecteddownward beyond the yokes,'the said tie bar being 2. A railroad tiecomprising a tie body of I v concrete,yokes each embodying a pair ofrail braces and an integral base connecting said braces and formed witha cushion receiving recess between the braces, a tie bar connecting theyokes and embedded in the tie body, cushion blocks having-notches toreceive portions of the yokes, and rail clamps having ceiving recessbetween braces which extend under the rail and rest upon thecushionblocks and upstanding portions which extend between the rail andbraces and interlock with the braces.

3. A railroad tie comprising a tie body of concrete, yokes eachembodying a pair of rail braces and an integral base connecting saidbraces and formed with a cushion rethe braces, tie bars connecting theyokes and embedded in the tie body, cushions fitting in said recessesand having notches to receive portions of the yoke, and rail clam shaving braces which extend under the rai and rest on the cushion blocks,upstanding portions which extend between the rail and braces, and lugson said upstanding portions which fit into notches in the braces. I

In testimony whereof I afiix my signature in presence of two witnesses.
